氧化还原反应贯穿于高中化学教材,其理论知识零乱、抽象、难懂,尤其是物质氧化性和还原性的判断.知识虽零散,但仍有规律可寻,现将常见的判断方法和理论依据总结归纳如下1.根据金属活动顺序表金属活动顺序表:K、Ca、Na、Mg、Al、Zn、Fe、Sn、Pb、H、Cu、Hg、Ag、Pt、Au. Oxidation-reduction reactions run through high school chemistry textbooks, and their theoretical knowledge is scattered, abstract, and difficult to understand, especially for the determination of oxidation and reduction of substances. Although knowledge is fragmented, laws are still available, and common judgment methods and theoretical basis are now available. Summarized as follows: 1. According to the metal activity sequence table, the metal activity sequence table: K, Ca, Na, Mg, Al, Zn, Fe, Sn, Pb, H, Cu, Hg, Ag, Pt, Au.
